[0023] like Figure 1 and Figure 3 As shown, in this embodiment, a positioning seat 7 is fixed on both sides of the conveying groove 2 on the top of the support installation box 1, and a storage port adapted to the shape of the pipe is opened on the top of the positioning seat 7, and the conveying assembly is used to convey the pipe to the positioning seat 7; a conveying groove 2 is opened on the support installation box 1, and the conveying assembly includes an electric push rod 31 arranged in the support installation box 1, and a conveying plate 32 is fixed to the telescopic end of the electric push rod 31, and a conveying port adapted to the shape of the pipe is opened on the top of the conveying plate 32, and the conveying plate 32 can be lifted to the outside of the support installation box 1 through the conveying groove 2, and a conveying drive component is installed at the bottom of the electric push rod 31, and the conveying drive component can drive the electric push rod 31 and the conveying plate 32 to move as a whole along the direction of the conveying groove 2; the driving assembly includes a traveling block 33 fixed to the bottom of the electric push rod 31, and a screw rod 34 is provided to connect with the traveling block 33, and one end of the screw rod 34 is connected to the stepping motor 35.

[0024] like Figure 1 and Figure 4 As shown, in this embodiment, the clamping assembly includes a clamping mounting seat 41. When the pipeline is sealed, the clamping assembly is used to clamp the pipeline to prevent the pipeline from shifting; the clamping assembly also includes a clamping fixing seat 42 fixed on the clamping mounting seat 41, and a positioning hole adapted to the shape of the pipeline is provided at the top middle end of the clamping fixing seat 42, and plug holes 43 are provided at both ends of the top of the clamping fixing seat 42.

[0025] like Figure 2 and Figure 7 As shown, in this embodiment, an inner extending shaft 63 is installed at the axis center of the sealing mold 61, and an inner sealing ring is fixed to the other end of the inner extending shaft 63. The outer diameter of the inner sealing ring is adapted to the inner diameter of the pipeline. Semicircular through holes are provided on the bottom end of the upper heating plate 51 and the top end of the lower heating plate 52. The size of the ring formed by the two semicircular through holes is adapted to the size of the inner extending shaft 63; a positioning ring 8 is fixed to one end of the two slides 54 close to the clamping assembly, and the pipeline can pass through the positioning ring 8.

[0026] The working principle of this utility model is as follows:

[0027] The cut pipe is above the initial position of the conveying plate 32. The electric push rod 31 starts to extend and drives the conveying plate 32 to lift the pipe upward. The stepper motor 35 starts to drive the screw rod 34 to rotate, and then drives the traveling block 33 and the conveying plate 32 to move toward the positioning seat 7. When the pipe moves to above the positioning seat 7, the electric push rod 31 contracts and drives the conveying plate 32 downward. After the pipe is supported by the positioning seat 7, the conveying plate 32 gradually separates from the pipe.

[0028] When the pipeline is transferred to the positioning seat 7, the pipeline is also on the clamping fixed seat 42. The cylinder 44 is started to drive the pressing seat 45 and the plug-in rod 46 downward until the plug-in rod 46 is inserted into the plug-in hole 43 of the clamping fixed seat 42, so that both ends of the pipeline are clamped by the clamping fixed seat 42 and the pressing seat 45. The cooperation of the plug-in rod 46 and the plug-in hole 43 plays a role in positioning and stabilizing the clamping, so as to effectively prevent the pipeline from shifting in subsequent processes.

[0029] Before the clamping stage begins, the driving assembly can drive the slide 54 to move a distance toward the pipe so that the positioning ring 8 is sleeved on the outside of the pipe to ensure positioning and normal operation of the clamping work.

[0030] The driving component (the driving component includes but is not limited to electric push rods, cylinders and motor screw parts, and devices that can achieve the same operation are also within the scope of protection of this application) starts to drive the slide 54 to move toward the direction of the pipeline, thereby driving the heating component to gradually approach the pipeline. At this time, the upper heating plate 51 and the lower heating plate 52 are in a merged state (such as Figure 6 As shown in the figure, as the slide 54 moves toward the pipe, the inner extension shaft 63 gradually extends into the pipe; after the upper heating plate 51 and the lower heating plate 52 come into contact with the pipe, the upper heating plate 51 and the lower heating plate 52 heat the edge of the pipe to melt the polyethylene material outside the pipe.

[0031] After heating is completed, the linear drive A55 and the linear drive B56 are started, driving the upper heating plate 51 upward and the lower heating plate 52 downward respectively to provide space for the pipeline to pass through, and the driving component drives the slide 54 to continue to move toward the pipeline until the sealing concave ring 62 of the sealing mold 61 contacts the end wall of the pipeline, and the molten polyethylene material is squeezed and wraps the exposed wire mesh; after sealing, the driving component drives the slide 54 to gradually move away from the pipeline and return to the initial position, and the inner extension shaft 63 also gradually moves toward the outside of the pipeline. When the inner sealing ring of the inner extension shaft 63 moves to the inner end of the pipeline edge, the sealing ring can bring out the polyethylene material that sticks to the inner wall of the pipeline due to heating, so as to effectively ensure the consistency of the inner diameter of the pipeline.

[0032] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements shall fall within the scope of the present invention as claimed.
